<br />COMPLIA�ICE WITH NATIONAL PRIMARY DRIfV�(iNG
<br />WATER REGULATIUNS
<br />The sources oi drinking wa[er �6ath tap water and hattled water� include rivers,
<br />lakes, streams, ponds, reservoirs, spnngs, and wells. As water travels over the
<br />suriace ot [he land ar [hrough�[he graund, itdissotves namrally-otcu�ring minerals
<br />and, in some cases, radiaacYive material, and can pick up su6sianses resulting tram
<br />the presence of animals ar from human activiry.
<br />Contaminants that may be present in source water include:
<br />• MicroSia! carttaminanls such 25 viruses and bacteria, which may come irom
<br />sewage treaiment plants, septic SysEemS, eg�icultural livestoc3c operauans, and
<br />wildl'rfe.
<br />• lnorgank canEamrnanls such as safts and metals, which can he naturally-
<br />occurring or resuii from urhan stormwaser runaff, industrial ar domestic
<br />wastewaier discharges, ail and gas productian, mining, or farming.
<br />• Pesticedes and herbicides, wh'rch may come from a var€ery oS sources such
<br />es agriculture, ur6an sFOrmwater runoH, and residenFial uses.
<br />• Organic chemrca! cnntaminanls, induding synihetic and vala5ile organic chemicals,
<br />which are 6y-producis of indusirial processes and petroEeum producuon, and cen
<br />slso come trom gas stations, urhan stormwaier runo(€, and septic sysrems.
<br />• Radioaeteve con[amMants, which can he naturally-occurring ur 6e ths
<br />resuh oi a�E and gas produc[ion snd mining activities.
<br />[n arder Ia en5ure that [ap water is saie io drink, the U. S. Environmental Protection
<br />Agency {EPpy prescribes regulations which limit the amount oi certain contamina�ts
<br />in water pravided by puhlic waYer systems. Foad and �rug Administration regulations
<br />establish limiis for contaminaats in hottled water which must provide the same
<br />prateciian tar pu6lic hea�th.
<br />�rinking we[er, induding hottEed water, may reasonably he expected to contafn
<br />a[ {east small amounts ot some con[aminants. The presence of contaminants does
<br />na[ necessarily indicate that water poses a health risk. Move information a6oat
<br />cansaminants and potential heahh eHecFS can be ohtafned by calling the
<br />EnvironmeMai Prmecti�n Agency's Sefe �rinking Water Hotline at 1-800-42$-4791.
<br />SPECIAL HEALiH INFURMATION
<br />Some penpls ma y 6e more vulnerable [o eontaminants irr drinking watsr tharr the
<br />genera! papulariorr. lmm�na-compromised persons such as persons wi[h cancer
<br />uRdergoing chemotherapy, persans who have undergone organ transpfarrts, peaple
<br />with H!V/A1D5 or otherimmune sys[em dlsarda�s, some alderty, and infaRts can �e
<br />pariicularly at risk (ram rniections. These Aeople should seek advice aLout drrnking
<br />water fram therr heafnc �ere praviders. EPri/CDC guidelines an apprapnate means ta
<br />lsssen the risk of iRfection by Cryptasporidiom are available from the Safe D�enking
<br />lNater Hotline ar hBaD-92b-479i.
<br />WHA7 ELSE CAN BE FOUND IN UUR �RINKfNG WATER?
<br />fn recent months, media autleis have addressed the presence of pharmaceutical
<br />and other househoid su65tance5 in aur [i�inking water.
<br />Note lha[ we meet ali EPA sFandards tor sate drinking water. Hawever, ihe EPA
<br />does not require [esting far pharmaceuYicals or hausehnld Items such as cafteine
<br />over the cnunter medicaFions, insect repefients, and cotinine {derived from nicotine,
<br />io-und in cigarene5l.
<br />When we drink coffee, smoke a cigarette, take medication, appry IoFion, fnseci
<br />repellent, and other products, our bndfes metaholize these substanres-6ut not
<br />comp€etely. These suhstances are excreted ar rinsed of! our Godies and end up in [he
<br />sewer system and are then Freased at a westewater iac'rlity. Orink€ng water treatment
<br />plants remo-ve most, 4ut nut all of these suhstances.
<br />A study condacted in 2U�0-2002 sested ior the presence ot arganic wastewater
<br />compounds at 65 sites thraughout the state, including the water entering and leaving
<br />the SPRWS ireatment plant. �etected concentretiorts of these compounds averaged
<br />less �han 3 parts per 6illion.
<br />Another smdy sugges�s the average persan wuuld need to drfnk 6etween hundreds
<br />to thousands o18-ounce glasses o( water every day aver a life[ime to intrease the
<br />risk [or cancer from [hese s�45tancES.
